Implement floor and ceil in assembly on i586
Fixes: https://github.com/rust-lang/compiler-builtins/issues/837

The assembly is based on

- 2043392793/lib/libm/arch/i387/s_floor.S
- 2043392793/lib/libm/arch/i387/s_ceil.S

Which both state

    /*

     * Public domain.
     */

Which I believe means we're good in terms of licensing.

libm

A Rust implementations of the C math library.

Usage

libm provides fallback implementations for Rust's float math functions in core, and the core_float_math feature. If what is available suits your needs, there is no need to add libm as a dependency.

If more functionality is needed, this crate can also be used directly:

[dependencies]
libm = "0.2.11"
